Add To BomPCF8574TS General Description
The PCF8574TS is an 8-bit I/O expander IC manufactured by Texas Instruments. It is designed to provide additional input/output pins to microcontrollers that have limited GPIO pins available. The PCF8574TS features an I2C interface, allowing communication with a wide range of microcontrollers and devices.The PCF8574TS has 8 bidirectional input/output pins that can be individually configured as either inputs or outputs. Each pin can sink/source up to 25mA of current, making it suitable for driving LEDs, relays, and other low-power devices. The PCF8574TS operates at voltages ranging from 2.5V to 5.5V, making it compatible with a variety of microcontrollers and power supplies.One of the key features of the PCF8574TS is its interrupt capability, allowing the microcontroller to be notified when an input pin changes state. This can be useful for applications that require real-time responsiveness to external events.
